When I first saw these the other day in the kickstarter list I though, hmmm, tidy. Nice design.
But at $30 and only 4 bits they just seem a bit over the top.
I was thinking I was sure I could make something up from a bit holder and some kind of t-piece from the workshop when I remembered I already had the right thing, for a lot less.

I have one of these in my house tool box. Just swap out 5 of the 6 bits for yur choice from your tool box and you have a tidy 65mm x 45mm x 18mm mini tool. The box has a keyed socket to take the bit holder.
Anyone got similar things?
